Abstract

Patente de Invenção: <B>"GáS INERTE PARA SOLDAGEM TIG"<D>. A invenção refere-se a um gás protetor para soldagem TIG de metais, especialmente aços de alta liga ou de baixa liga, cuja condutividade térmica seja menor que a do alumínio. O gás da invenção consiste em argónio, hélio e hidrogênio e permite melhoras significativas a serem feitas na estabilidade do arco elétrico, na velocidade da soldagem, oxidação da superfície da solda e área adjacente, performance de fluxo e aparência da solda.Invention Patent: <B> "GAS INERT FOR TIG WELDING" <D>. The invention relates to a protective gas for TIG welding of metals, especially high-alloy or low-alloy steels, whose thermal conductivity is less than that of aluminum. The gas of the invention consists of argon, helium and hydrogen and allows significant improvements to be made in the stability of the electric arc, in the welding speed, oxidation of the weld surface and adjacent area, flow performance and appearance of the weld.
